March 8 is International Women's Day and to celebrate we've combed the archives of Virtual Motor City and come up with these 30 empowering images. The photos span the first and second world wars and show women who went to work in crucial manufacturing jobs in factories and plants to aid in the war effort. Rosie the Riveter may be the go-to feminist symbol for women's employment, but these real photos of Detroit women hard at work are even more inspiring today.
